Title:
SUPER ICE TEMPERATURE FRESH-KEEPING APPARATUS AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/220448
Kind Code:
A1
Abstract:
A super ice temperature fresh-keeping apparatus and a control method therefor. A refrigerator comprises a main body and a cover plate; the main body comprises an air circulation cavity, an ice slurry cavity, and a food storage cavity; one side of the food storage cavity is open; the ice slurry cavity covers the outer side of the food storage cavity; the air circulation cavity covers the outer side of the ice slurry cavity; the cover plate is sealingly connected to the main body in a manner of opening and closing the food storage cavity; the ice slurry cavity is filled with a freezing point conditioner; the air circulation cavity refrigerates the ice slurry cavity by means of cold air supplied by a matched refrigeration device. The characteristic that the freezing point conditioner absorbs heat to change a phase without changing the temperature of the freezing point conditioner is used to maintain a constant temperature of the food storage cavity, so that the temperature fluctuation is small, the control precision is high, and the super ice temperature storage of fresh products is easily achieved.
